Patented May 23, 1916..

Application led February 8, 1915. Serial No. 6,765.

To all whom z't may concern:

Be it known that I, LARs LARso-N, a citizen ofthe United States, and aresident of the city of Chicago, county of Cook, and State of Illinois,have invented certain new and useful Improvements in Slag-DisintegratingApparatus, of which the following is a specification.

My invention relates to improvements 41n slag disintegrating apparatus,and has for its object the production of mechanism of this characterwhichv will be of improved construction and efficient in operation.

A further object is the production of slag disintegrating apparatus inwhich the cooling of the slag before disintegration will be effectedwithout the necessity of subjecting the molten slag to the direct actionof water.

Other objects will appear hereinafter.

Theinvention consists in the combinations and arrangements of partshereinafter described and claimed. y

The invention will be best understood by reference to the accompanyingdrawings forming a par-t of this specification, and in which i Figure 1is a side elevation of a slag'disintegrating apparatus'embodying myinvention, Fig. 2 is a top plan view of the same, Fig. 3 is a sectiontaken on substantially line m-.r of Fig. 1, Fig. 4 is an enlargedcentral vertical section of one end of the apparatus, and Fig. 5 is anenlarged detail section taken on line g/-jz/ of Fig. 4. y

The preferred form of construction, as illustrated in the drawings,comprises a reservoir l into which the molten slag to be treated isdeposited. The reservoir 1 is provided at its front end with an outletopening 2 which is controlled by a vertically slidable gate valve 3which is mounted between guide flanges 4 provided upon the front wall ofsaid reservoir. The front end of the reservoir is reduced at theapproach thereof to the discharge opening 2. The gate valve 3 m ismanually controlled by means of a stem for moving the p jected at oneend for the accommodation of a pulley 13, as clearly shown in Fig. 2,through the medium of which connection may be made for driving the same.Mounted fortravel around the sprocket wheels 11 and 12 are two spacedendless sprocket chains 14.

Arranged upon the inner sides of the lateral walls of tank 8 areinwardly projecting angle irons 15 for engagement with the under `sidesof chains 14 to support the same in the travel of said chains, as willbe readily understood.

,Arranged between the chains 14 is a plurality of flat rectangularplates 1G arranged edge to edge, the lateral edges of said plates havingupwardly turned flanges 16 which are fastened to said chains, as shown.Re* inforcing angle irons 17 are provided at the under sides of plates16 to prevent warping or sagging of said plates, as will be readilyunderstood. Provided at the front edge of each plate 16 is a downwardlyoset iange or lip 18 adapted to overlap with or engage under therearward edge of the next forward plate, as clearly shown in Fig. 4, inorder to maint-ain said plates in proper alinement and prevent theforward edge of any of said plates projecting above the rearward edge ofthe next forward plate, the reason for this precaution being hereinaftersetforth as will appear. The arrangement is such, as will be seen, thatan elongated longitudinally movable endless platform is constituted bythe chains 14 and the members 16 which, when the apparatus is in use,passes immediately below the outlet opening of the reservoir 1.

Arranged below the upper portion of the endless platform immediatelyforward of the outlet opening of the reservoir 1 is a spraying nozzle 19which is constituted by a substantially U-shaped pipe having openvthatis the plates 1G.

ings at its upper side through which the cooling liquid supplied to saidpipe is adapted to pass in the form of a great number of small streamsor sprays for contacting with the under sides of plates 1G` in order tocool the same. The nozzle 19 is connected at one end with a supply pipe2O which leads to any suitable source of cold water supply. A

atr23 to one end of the bottom of theV trough 22 is a plate 24 soarranged that the outer or free end thereof rests loosely upon theupperside of the traveling platform, In order to insure a closeengagement between the upper sides of Y said plates and the front edgeof said plate 24. the under side of said edge of said plate it beveled,as clearly shown in Fig. 4. Also arranged at the entrance end of thetrough 2'2 are divergent laterally projecting plates Q5 secured. bymeans of bolts 26 and cooperating -nuts, to supporting plates 27 rigidlysecured to suitable adjacent supporting structure. The bolts 2G engagevertically extending elongated slots 2S formed in the plates Q5. asclearly shown in Fig. 5, which permit of vertical adjustment of saidplates in order to adjust the lower edges thereof relative to the upperside of the platform.

In the operation of the apparatus, the slag which is deposited upon theplatform from ythe outlet opening of the reservoir l will be cooled byreason of the cooling of the plates 1G through spraying thereof by thenozzle 19'. As the cooled and therefore hardened slag reaches the plates24 and 25, the same will be scraped thereby from the upper side of theplatform and directed toward the entrance end or mouth of trough 92. Inorder to insure the thorough scraping of the platform by the plates 25,the lower edges of the latter are bent forwardly at an angle, as clearlyshown in Fig. 5, said bending of said edge rendering the removal of theslag from t-he platform more easy and with less resistance. lips 1S atthe front edges of platform plates 16, the possibility of engagement ofsaid edges of said plates with the scraper plates 24; and 25 isprecluded since. as above'pointed out, with this construct-ion it isimpossible for said edges of said plates to project above the rearwardedges of the next forward plates. Arranged above the respective ends oftrough QQ are shafts Q9 and 30 upon which are mounted pairs of spacedsprocket wheels 81 and 32I respectively. Traveling Through the provisionof the around the sprocket wheelsl and 32 are two spaced sprocket chains33'upon which are carried scraper members or buckets 8l adapted` uponmovement of the chains 33 to successively enter and travel along thetrough 22 in order to carry the slag directed V the adjacent lateralwalls of the trough and' thus interfere with the free passage of saidbuckets through'the trough. The shaft 30 is extended at one end toaccommodate a -pulley 37 through which attachment may beV made to asource of power for driving of said shaft, as will be Vreadilyunderstood. The slag which is carried rearwardly in the trough 22 by thebuckets 35 when carried beyond the rearward' end of said troughdropstherefrom into a hopper 38 arranged below said end of said trough,as clearly shown in the several views. Arranged at the lower end of saidhopper are disintegrating rollers 39 through the medium of which theslag, which is deposited into said hopper will be crushed or granulatedto the desired degreepof tineness, as will be readily understood. Theendless platform is of such length that there is considerable slackinthe Y This compartment in the operation of the apparatus is suppliedwith cooling water and therefore in the passage of the platform throughsaid compartment, said platform will be subjected to a bath to effectcooling of the same. An over-flow pipe 40 is provided in the side ofcompartment 8 forV de'-l termining the level of the cooling water con*tained therein anda drainpipe 41 registers with the bottom of saidcompartment for entirely draining the same when desired 'in order toremove any sediment which may gather therein.

In order to insure against the lodging'of any particles of slag orforeign matter upon the lips or flanges 1S so as to thus prevent properseating of the rearward edges of the to effectively clean the jointsbetween the plates before the same are closed which occurs immediatelyafter said plates pass from engagement with the sprocket wheels 1l. Thenozzle 42 is supplied with water through a pipe 43 which connects withthe supply pipe 20. The arrangement is such, as will be seen, that thevalve 2l serves as a control for both nozzles 19 and 42. The water whichis discharged from said nozzles drips down the sides of the tank 8,accumulating in the cooling compartment 8 which is thus supplied Withthe water for cooling at this point, as above described. The bottom ofthe tank 8 is. inclined in both directions toward the compartment l8 sothat the water will readily drain into the latter.

While I have illustrated and described the preferred form ofconstruction for carrying my invention into effect, this is capable ofvariation and modification without depaiting from the spirit of theinvention. I, therefore, do not wish to be limited to the precisedetails of construction set forth, but desire to avail myself of suolivariations and modifications as come Within the scope of the appendedclaims.
